Xen Project Hypervisor Roadmap/4.6

Rather than try to predict precisely what will make it into what release, we are following an approach from the Agile world and call all uncompleted features the "Backlog". We are however keeping track who is doing what, what is completed and what is almost completed in this wiki page. For ongoing work check out the Process section of this document.

Release Manager

We confirmed Wei Liu from Citrix as Release Manager for Xen 4.6 : see e-mail thread

Roadmap

As in the past, roadmap discussions will mostly happen on the xen-devel mailing list (see below). The convention is that our release manager will regularly post an e-mail called Xen 4.6 development update on the xen-devel list and that community members respond to it.

The Process

You can find information on how we make relases in this blog post. We also attached a few pictures for your convenience.
